About this study

Official title: Endothelin in the Coronary Circulation in Early Atherosclerosis in Humans

Qualifying patients who are scheduled for angiogram with endothelial function testing are approached to participate in this protocol (consent form reviewed with patient). Those who are willing to participate will have additional measurements taken during their angiogram as part of this protocol. Patients who are diagnosed with Endothelial Dysfunction as a result of a clinically indicated angiogram will be eligible to participate in a 6 month medication trial (Atrasentan vs. placebo - randomized, blinded trial). Patients are monitored closely during the 6 month trial via phone calls and blood testing for assessment. At the end of the 6 months they return to Mayo for a repeat angiogram to assess endothelial function for any changes or improvements.

Read the detailed description

Aim I: To determine the activity of the endogenous endothelin system in the coronary circulation in humans with coronary endothelial dysfunction and atherosclerosis risk factors. Aim II: To assess the potential of chronic endothelin receptor antagonists to improve preexisting coronary endothelial dysfunction and myocardial perfusion in humans and Aim III: To assess the effect of chronic endothelin receptor antagonism on the endogenous nitric oxide system in association with oxidative stress in humans with early coronary disease risk factors.

Being tested

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Atrasentan in people with Endothelial Dysfunction, run by Mayo Clinic at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 30 Apr 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To find out what effects (good and bad) the medication Atrasentan has on the heart (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00271492, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Apr 2010.
